Yes, methamphetamine is illegal in California. State law treats personal possession as a misdemeanor and treats selling, transporting, or manufacturing meth as felonies carrying multi-year prison sentences, and the same conduct can be charged federally with mandatory minimums that a judge cannot reduce. Voters tightened the rules again in November 2024 when the new Proposition 36 created harsher options for repeat drug offenders, partially reversing the leniency of the 2014 Proposition 47.
Simple Possession
Possessing methamphetamine for personal use is a misdemeanor under Health and Safety Code 11377. Prosecutors must show you had a usable quantity, knew it was there, and knew what it was. A conviction carries up to one year in county jail and a fine of up to $1,000.1California Legislative Information. California Health and Safety Code 11377
Simple possession was a felony before 2014. Proposition 47 reclassified it as a misdemeanor for most people, but it can still be charged as a felony if you have a prior conviction for murder, a sex offense requiring registration, or another serious or violent felony punishable by life in prison.1California Legislative Information. California Health and Safety Code 11377
The 2024 Proposition 36 Change
The new Proposition 36 added another path to felony charges. If you have two or more prior convictions for drug crimes such as possessing or selling controlled substances, prosecutors can now charge methamphetamine possession as a “treatment-mandated felony” instead of a misdemeanor. The court orders drug or mental health treatment, and completing treatment results in dismissed charges. Failing or refusing treatment can result in up to three years in state prison.2Legislative Analyst’s Office. Proposition 36 Ballot Analysis
Being Under the Influence
California also criminalizes simply being under the influence of methamphetamine, separate from possessing it. Health and Safety Code 11550 makes this a misdemeanor punishable by up to one year in county jail. Prosecutors do not need to find any drugs on you. Signs of impairment and chemical testing can support the charge on their own.
Possession for Sale
Possessing methamphetamine with intent to sell is a felony under Health and Safety Code 11378, carrying 16 months, two years, or three years in jail or prison. No actual sale needs to happen. Prosecutors prove intent through circumstantial evidence: the quantity found, baggies or scales, large amounts of cash, pay-owe sheets, or multiple cell phones.3California Legislative Information. California Health and Safety Code 11378
The 2024 Proposition 36 also requires certain drug-sale felonies to be served in state prison rather than county jail, depending on the person’s criminal history and whether sentence enhancements apply.2Legislative Analyst’s Office. Proposition 36 Ballot Analysis
Selling and Transporting
Selling, transporting, furnishing, or giving away methamphetamine is a felony under Health and Safety Code 11379, punishable by two, three, or four years in prison. The statute covers not just completed sales but also attempts and offers to sell or transport. Transporting the drug across more than two county lines can increase the sentence significantly.4California Legislative Information. California Health and Safety Code 11379
Manufacturing
Manufacturing methamphetamine is one of the most heavily punished drug offenses in the state. Health and Safety Code 11379.6 makes producing, converting, or processing the substance a felony carrying three, five, or seven years in prison and a fine of up to $50,000.5California Legislative Information. California Health and Safety Code 11379.6 Meth labs also pose fire and toxic-exposure risks, which often leads to additional charges like child endangerment or hazardous-waste violations when other people are present.
Extra Time for Large Quantities
Health and Safety Code 11370.4 adds mandatory prison time on top of the base sentence when large quantities of methamphetamine are involved in a sale, transport, or manufacturing conviction. A person convicted under HSC 11378 or 11379 with more than one kilogram receives an additional three years in prison.6California State Legislature. California Assembly Bill 701 (Chaptered) – Section 11370.4 The enhancements escalate with weight: four kilograms or more triggers five additional years, with the stiffest penalties at the highest weight tiers. Quantity is often the single biggest factor in how a case plays out.
When Federal Charges Take Over
Methamphetamine cases can also be prosecuted federally. This typically happens when the quantities are large, the operation crosses state lines, or a federal agency like the DEA made the arrest. Federal law classifies methamphetamine as a Schedule II controlled substance.7Office of the Law Revision Counsel. 21 USC 812 – Schedules of Controlled Substances Federal sentences are much harsher than California penalties and carry mandatory minimums that a judge cannot go below.
The thresholds under 21 U.S.C. 841 break down by whether the methamphetamine is pure or in a mixture:
- 50 grams pure or 500 grams of a mixture. A first offense carries a mandatory minimum of 10 years and a maximum of life in prison. With one prior serious drug or violent felony conviction, the minimum rises to 15 years. Two or more priors trigger a 25-year minimum.
- 5 grams pure or 50 grams of a mixture. A first offense carries a mandatory minimum of 5 years and a maximum of 40 years. One qualifying prior raises the minimum to 10 years with a maximum of life.
If someone dies or suffers serious bodily injury from the drug at either threshold, the mandatory minimum jumps to 20 years.8Office of the Law Revision Counsel. 21 USC 841 – Prohibited Acts A
Diversion Options
California allows certain defendants to avoid a criminal record entirely through diversion. Under Penal Code 1000, someone charged with simple possession who has no prior drug convictions and whose offense involved no violence can enter a deferred-entry-of-judgment program. The program involves court-supervised treatment, drug testing, and counseling. Completing it results in dismissed charges, so no conviction appears on your record.
The treatment-mandated felony created by the 2024 Proposition 36 functions as a separate diversion track for repeat offenders. Unlike PC 1000, it is available to people with two or more prior drug convictions, but the stakes are higher: failure to complete treatment can lead to state prison rather than the county-jail maximum that misdemeanor possession carries.2Legislative Analyst’s Office.

Consequences Beyond the Courtroom
A methamphetamine conviction creates problems that outlast any jail sentence. The collateral consequences can be harder to recover from than the conviction itself.
Immigration
For non-citizens, a methamphetamine conviction is one of the most dangerous criminal offenses possible. Federal immigration law makes any person convicted of a controlled-substance violation deportable, with no exception for simple possession. Marijuana has a narrow exception for a single offense involving 30 grams or less; methamphetamine does not. A conviction at any point after admission to the United States triggers deportation eligibility, and drug convictions generally also bar relief like cancellation of removal.9Office of the Law Revision Counsel. 8 USC 1227 – Deportable Aliens
Federal Housing
Anyone convicted of manufacturing methamphetamine on the premises of federally assisted housing faces a permanent ban from both public housing and Housing Choice Voucher (Section 8) programs. This is one of the few lifetime disqualifications in federal housing law, and housing authorities have no discretion to waive it.10HUD Exchange. Are Applicants With Felonies Banned From Public Housing or Any Other Housing Funded by HUD?
Commercial Driving
A methamphetamine offense can end a commercial driving career. Federal regulations disqualify a CDL holder for one year after a first conviction for being under the influence of a controlled substance, and three years if the person was hauling hazardous materials. A second drug-related conviction results in a lifetime disqualification. Using any vehicle to manufacture or distribute a controlled substance triggers an immediate lifetime disqualification with no possibility of reinstatement, even after 10 years.11eCFR. Subpart D – Driver Disqualifications and Penalties
Employment
The Drug-Free Workplace Act requires every federal contractor to maintain a workplace free of controlled substances and to take action against employees convicted of drug offenses. An employee working on a federal contract must notify the employer of any drug conviction within five days, and the employer must report the conviction to the contracting agency within 10 days.12Office of the Law Revision Counsel. 41 USC 8102 – Drug-Free Workplace Requirements for Federal Contractors Beyond federal contractors, many California employers in healthcare, education, transportation, and law enforcement conduct background checks that surface drug convictions, and professional licensing boards routinely deny or revoke licenses based on controlled-substance offenses.
